This invention relates to thev spinnerettes used ,in the manufacture of artificial silk or the so-called rayon products'. These consist of metallic caps or nozzles mounted on Irotary spindles and provided in their closed ends with perforations through which the usual chemical composition is forced or'producing the artificial silk threads or filaments.

The object of my invention is the provision of a spinnerette which can be produced at a comparatively low cost and Which, while resisting the action of acid and alkaline solutions, has the reruired hardness and strength, and is sullicient y malleable to permit its easy stamping without danger of cracking or fracture.

To that end the invention consists in making the spinnerette of an alloy of gold and nickel.

lIn the accompanying drawingsz Figure 1 is a side elevation of a spinnerette embodying the invention. Figure 2 is a longitudinal section thereof.

Similar characters of reference indicate corresponding par-ts in both the views.

The spinnerette has the form of the usual cap or nozzle 10 having a base flange 11 and provided in its head wlth a plurahty of perforations 12 for the passage of the chemical composition or pulp which produces the artificial threads. The improved spinnerette is formed or stamped from an alloy composed of pure gold or twenty-four karat gold and i nickel, preferably in the proportion of eighty to ninety-nine percent of gold and one to twenty percent of nickel. These metals are heated in a cruci'ble or furnace to sufliciently high temperature to :form a homogeneous alloy, after which the' alloy is cast in a suitable mold and rolled into sheets which are 40 then stamped in appropriate dies to form the spinnerettes.

While being light, strong, hard and durable, these improved spinnerettes are unaffected by the acids or chemical solutions used for producing the artificial silk or rayon products and they can be produced at considerably less cost than the spinnerettes heretofore used. l

At the same time, the alloy of which the spinnerettes are made, possesses the necessary malleability to permit them to be easily stamped.

I claim as my invention 1. A spinnerette constructed of' an alloy 55 composed of gold and nickel.

2. A s innerette constructed of an alloy compose predominantly of gold and a materially less percentage of nickel.

3. A spinnerette constructed of an alloy composed of from eighty to ninety-nine percent 'of gold and from one to twenty percent of nick REGINALD V. WILLIAMS.
